This is the Two Direction Automatic Label Rewinding Machine. It is an automated machine that collects and winds freshly printed labels. It has an adjustable speed control so you can set the speed to be the same as your printer. It efficiently collects and winds the label into a 3” roll which makes storage convenient. It can wind the label rolls both inside and outside. Without this rewinder, you would have to collect up the labels by hand. It makes things handy, organized, and will save you time. When you’re ready, it will also unwind the role of labels. Companies that print out packaging labels, barcode labels, or security labels for electronic manufacturers, pharmaceutical companies, or grocery stores employ this product for its speed and efficiency. (Please note that you need to set the speed to 3 level at least to make the motor work)This is an easy to use and quality product offered by US Solid.
